Specification of Letters Patent.

Patented Jane 2, 1914. Serial No. 716,297.

To all whom. it may concern Be it known that I, JACOB F. BENNETT, acitizen of the United States, residing at Herrick, in the county ofShelby and State of Illinois, have invented certain new and usefulImprovements in Road Graders and Scrapers, of which the following is aspeciiication.

This invention relates to machines for making roads, and its object isto provide an eflicient machine of this kind which can be operated as agrader as well as a scraper, and which is simple in construction.

"With these objects in view, the invention consists in a combination andarrangement of parts to be hereinafter described and claimed, referencebeing had to the accompanying drawings forming a part of thisspecification.

In the drawings-Figures 1 and 2 are plan views showing the machinearranged for different kinds of work. Fig. 3 is a section on the line3-3 of Fig. 1. Fig. 4 is a rear end view of the machine. Fig. 5 is across-section on the line 55 of Fig. 1.

Referring specifically to the drawing denotes the mold-board, and 11 thelandside of the machine; said parts being rigidly connected bycross-braces 12. The moldboard is connected to the landside a shortdistance back of the forward end thereof, which leaves a short section13 of the landside extending forward from the machine, which preventsthe clods and dirt from getting past the landside. The braces 12 supporta platform 14L for the driver, and also standards 15 carrying a seat 16.The mold-board and landside diverge in the direction of the rear end ofthe machine.

Art the front end of the machine is a caster-wheel 17 carried by across-bar 18 extending between the mold-board and the landside. The rearend of the machine is supported on a caster-wheel 19 carried by a fork20, the stem of which is swiveled in a support 21 hinged at 22 to themold-board, to swing in a vertical plane. The rear end of the landsidecarries a hand lever 23 provided with a suitable locking device 24:, andhaving a bend 25 at one end which is connected by a link 26 to a liftingbar 27 which is hinged at 28 to the mold-board to swing in a verticalplane. The lifting bar is connected intermediate its ends by means of alink 29, to the free end of the support 21. A link 30 loosely connectsthe support to the rear brace 12, and a similar connection 31 isprovided between said brace and the lifting bar.

It will be evident from the foregoing that the caster-wheel 19 may bereadily raised or lowered upon operating the hand lever 23.

he front end of the landside is beveled at the bottom so that it maypass freely over obstructions, and to said end of the landside isconnected one end of a draft chain 32 the other end of which latter isconnected to the mold-board, near the rear end thereof. A draft bar 33is adjustably connected to the chain 32 by means of a hook-clevis 3a togive the mold-board any desired angle to the line of travel of themachine.

The mold-board is fitted with a scraping share 35 which is sharpened onboth edges so that it may be reversed. The rear end of the landsidecarries a small blade 36 which extends a short distance below the sameand is designed to cut into the ground for the purpose of holding thelandside to run steady and straight and not slide sidewise.

To the rear brace 12 is fastened a beam 37 which extends across the topof the landside and projects a short distance therefrom. The purpose ofthis beam is to provide for the attachment of a plow 38 as shown in Fig.2, said plow being hitched to the projecting end of the beam, whichlatter has apertures 39 for fastening the plow clevis so. The beam 37 isconnected by a brace rod 41 to the landside. The plow travels behind themachine, on the landside thereof, and the attachment enables the plow toget close up to a bank where a plow cannot get with a team hitcheddirectly thereto. This makes the machine very convenient for workinghills.

Fig. 1 shows two of the machines working together and connected at theirrear ends by a rope or other suitable connection 42 so that they areheld parallel and prevented from slipping away sidewise from the dirt.The two machines hitched together as shown bring the dirt from theditches to the center of the road. One machine counteracts the other,and the dirt is drawn from both sides of the road.

The wheel 19 prevents the share 35 from. running too deep. The depth isreadily regulated by adjusting the wheel as hereinbefore described, andby means of said wheel the mold-board may be elevated above the groundto drop the accumulated dirt in front thereof.

The machine herein described makes an eflicient road grader and level.It is simple in construction and does the work well. The plow first runsa furrow, and the dirt is then run from the furrow toward the middle ofthe road. The plow then makes another furrow, and the dirt is again runtoward the middle of the road, and so on until the road is ready forharrowing. The plow can be run close to a bank to widen the road, and atthe same time make a ditch for draining water off the road. If themachine is to be used as a scraper, the hitch will be changed so thatthe mold-board runs almostsqnare to the dirt with an angle just enoughto force the dirt sidewise.

I claim:

A road machine comprising a landside, a

mold-board extending therefrom, a crossbrace connecting the landside andmoldboard, a support hinged to the mold-board behind the cross-brace toswing in a vertical plane, a wheel carried by the support, a hand levermounted on the landside and having a bend, a vertically swinging liftingbar hinged to the mold-board above the support, a link connecting thelever bend to the lifting bar, a connection between the lifting bar andthe aforesaid support, a loose connection between the cross-brace andthe support, and a loose connection between the cross-brace and thelifting bar.

In testimon whereof I aiiiX no si nature in presence of two witnesses.
